FENCE-POST FULLER.

This pullers.

An important object of this invention is to produce a device of thischaracter, which may he operated a jack and will intermittently grip andrelease the post, the oper# ating handle is moved downwardly andupwardly, so that the post is forced .upwardly step hy step without anydamage thereto.

A further object of t-he invention is to provide a device of thischaracter which may he very cheaply and readily manufactured, which willbe durable and efficient in service and a general improvement in th art.

These and other objects I attain by the construction shown in theaccompanying drawings, wherein for thepu'rpose of illustration is showna preferred embodiment of my invention and wherein invention relates tofence post Figure 1 is a slde elevation of a fence post pullerconstructed in accordance with my invention applied to a post to extractthe same from the ground;

Figure 2 is an enlarged vertical sectional view through the operatingend ofthe eX- tractor;

Figure 53 is Figure 1;

Figure i is a section similar to that shown in Figure 2, hut with thedog` reversed for use in connection with a different type of post;

Figure 5 is a view similar to (hat shown in Figure 3 showing the devicein use with a different type of post.

Referring now more particularly to the drawings. the numeral 10generally designates a lever pivotally connected with a ground engagingfoot 11 hy arms 12 arisingI from the foot. The lever 10 is at presentillustrated as composed of a wooden handle section 13 and an extensioncomprising plates 14. secured to opposite sides of the handle 13 andprojecting beyond the ends thereof. One of the bolts 15, which securethe plates 14 in position upon the handle, serves as a pivot for theupper ends of the arms 12. 1

` Directed through the ends of the plates 14 is a pivot 15 for aU-shaped dog 16. Through the Li-shaped deg 16 is directed a pivot holt17 receiving the arms 18 of a U- shaped clevis 19. The cross har 2O ofthe U-shaped clevis 19 is shaped to correspond a section on the line3h?) of to the shaping of the post, with which it is to he employed. lnFigure 3, the clevis is shown as constructed for use with angle ironposts and the cross bar is of angular formation, while in Figure 5, theclevis is adapted for use with channel or T-iron posts and is flat. Thedog 16 has the ends of the arms thereof bevel-cut, as indicated at 21.The cross bar 22 of this dog is V-shaped and at an angle to thelongitudinal centers of the arms 23 similar to the angle at which thearms 21 are cut.

In the use of the device, and end of the dog being tion7 the upper endof the between the clevis and dog and the entire device slid downwardlyuntil the foot 11 comes in engagement with the ground. The handle end ofthe lever is then oscillated vertically and as this handle is depressed,the dog will tend to swing about its pivot upon the bolt 17, so that thenose 2-1 or 25 of the operating end eno'ages against the adjacent faceof the post and acts. with the cross bar 20`of the clevis, to clamp thepost, so that as the post confronting end of the handle 10 rises, thepost rises therewith. As the handle end of the lever is moved upwardly.the frictional engagement of the clevis with the post will tend toretard downward movement thereof. with the result that the pivot 15 willmove downwardly with respect to the pivot 17, thus rocking the dog 16.yso that the nose 24 or 25 is disengaged from the post and the cl'evisreleased from the p0st, so that it may slide downwardly thereon.

It will'. of course, he understood that the dog 16 will he reversed whenemployed with angle iron posts from the position which it will occupywhen it is employed with either T-iron or channel iron posts. liVhenemployed with 'an angle iron post. the cross har end 25 confronts thepost and when employed with the latter types of posts, the ends of thearms confront the posts, the pivot pin 17 being engaged in the properopenings 26 of the dog arms. When used with channel iron posts, thenoses 24 of the arms engage the inner face of the base of the channel,while the cross bar of the clevis engages the outer face thereof andwhen employed 'with T-iron posts, the ends of the arms engage the headof the T at opposite sides of the stem thereof, while the clevis engagesthe outer face of the head ot' the the proper clevis arranged 1nposipost is extended T. It will, of course, be understood that insteadof employing` the reversible'dog-16v as illustrated, separa-te dogs maybe' employed, if so desired.

Since the construction forth is capable of a certain range of changeland modification Without materially departing trom the spirit of theinvention, I do not limit myseli:l to sueh specific structiire `1 exceptas hereinafter claimed.

I claim l. In Combination, a lever,` a ground enaging' fulcruni thereforand pernianentlyY vivotally connected therewith, a U-shaped ieg, a pivotextending; through the arms ot the dog,r adjacent one end thereof andthrough one end of the lever,;a` pivotcarried bythe dog at theapproximate center thereot, a elevis having arms engaging` said pivotand a cross bar confronting the" free end ot' the dog. the tree endofthe dog and cross har of the elevis being' constructed forhereinloei'ore set clamping engagement with opposite :faces of a fencepost.

2^. In combination, gaging ulcrum therefor and permanently pivotallyconnected therewith, a U-shaped dog, a'pivot extentnpfthrough the armsof the dogadjacent one end thereof and through one end ot the lever, apivotearried by the dog-v at the approximate center thereof7 a clevishaving arms engaging` said pivot and across bai' confronting the freeend et the dog, the tree end of the dogand cross har of thev 'c'levisbeing constructed for clamping` engagement with opposite faces of atenceV post, the ends of the arms remote from the cross har of saidelevis being bevelcut vto produce projecting 'noses equally spaced fromthe pivot, ,the cross bar of the dog having a V-shaped projecting. nose.

In testimony whereof I hereunto ax my signature. o
